[CR] Comment on the crank arm break please

Hello,

Please take a look at the photos in this blog entry: http://449km.blogspot.com/2010/01/ooooof.html

I'd like your comments on exactly what the darker section on the break would mean. The crank in question is a gold anodized Campy NR crank. The crank had not seen many miles at all, and had not been abused.
